Figure 2. The expanding complexity and reach of threats
Growing threats
Meanwhile, threats continue to grow
in both number and sophistication.
For example, 280 million malicious
programs, 134 million web-borne
infections and 24 million malicious
URLs were detected — all in just one
month.5 Moreover, the complexity and
range of those threats has morphed
from “simple” viruses and worms to
full-fledged cyber-terrorism and other
attacks using sophisticated tactics such
as SQL injection (see Figure 2).
Limited IT staff and budget
Finally, despite these growing pressures
on endpoint protection, IT staff and
budgets grow marginally or not at all
(see Figure 3), making it difficult to
keep your environment protected. For
instance, StatCounter found that more
than 16 percent of PCs worldwide
still have Windows XP installed even
though Microsoft’s support has
already ended — a clear security and
compliance risk.
Part of the problem is that day-to-day
IT operations costs are so high: an IDC
white paper sponsored by Dell found
that the average deployment cost per
PC is $615, and WIPRO pegged the
annual cost of supporting a laptop at
$969 (assuming a five-year refresh rate).
Such costs can quickly erode whatever
budgets IT organizations have.

Protecting your environment has
never been more important
Understanding the importance of
mastering these challenges and
protecting your environment requires
only glancing at the headlines.
Organizations are breached every day
by attacks on their networks and also
in other ways, such as theft of laptops
containing confidential data (see Figure
4). As a result, organizations lose not
only valuable intellectual property
but also the customer trust that is the
foundation of any business.
Since these controls were derived from
the most common attack patterns and
vetted across a broad international
community of governments and
industries, with very strong consensus
on the resulting set of controls, they
serve as the basis for immediate, highvalue action.
The 20 Critical Security Controls, as
detailed in “The Critical Security
Controls for Effective Cyber Defense,
Version 5.0,” are:
1. Inventory of authorized and
unauthorized devices
Endpoint protection through the
SANS 20 Critical Security Controls
2. Inventory of authorized and
unauthorized software
A set of controls to guide highvalue action
3. Secure configurations for hardware
and software
How, then, can organizations best
protect their IT environments? In 2008,
the National Security Agency (NSA)
asked the same question, and began
assessing which controls have the
greatest impact in improving risk posture
against real-world threats. In concert
with a global consortium of agencies
and experts from private industry, the
SANS Institute created a list of 20
actionable controls with high payoff.
